The Bard 910-1894 Airflow Switch Assembly is an OEM safety and proving switch used in Bard wall-mounted HVAC equipment to confirm that required air movement is present before allowing certain heating or cooling functions to operate. When the blower establishes airflow, this switch changes state and helps the unit control sequence run correctly; if airflow is restricted from a dirty filter, blocked return, or failing blower, the switch can open and prevent nuisance trips or component damage. Use Bard 910-1894 to restore proper airflow verification and reliable operation, and confirm part compatibility by matching the full part number to your unit model and serial number information before ordering.
